IonPac AS24 Anion Exchange Column

The IonPac AS24 hydroxide selective anion exchange column is specifically designed for haloacetic acids in drinking water prior to MS or MS/MS detection.  The capacity and selectivity allows for the analysis of haloacetic acids in drinking water at the low µg/L concentration.  The AS24 column is the specified column in U.S. EPA Method 553.

  • Recommended anion-exchange column for the analysis of haloacetic acids in drinking water prior to MS or MS/MS detection.
  • Specified column for U.S. EPA Method 553.
  • High capacity: 140 µeq per column.(2 x 250-mm column).
  • Determine HAAs in high-ionic strength matrices without sample pretreatment.
  • Operate at ambient or elevated temperatures.  Column selectivity is optimized for a 15°C operating temperature to ensure reproducible recoveries for haloacetic acids in drinking water.
  • Compatible with HPLC organic solvents to enhance analyte solubility, modify column selectivity, or for effective column clean up.
